[0032] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0033] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0034] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0035] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0036] The embodiments of the present disclosure provide an electronic device and a control method. Before introducing the technical solutions provided by the embodiments of the present disclosure, the related technologies involved in the present disclosure are first described.

[0037] In the related art, currently, dynamic photography is usually achieved by using an external mobile platform or manually controlling the movement of the photographic device during the shooting process, which results in a decrease in user experience.

[0038] For example, dynamic time-lapse photography uses additional photography equipment, such as a stabilizer, a mobile gimbal, etc., to assist in photography, which not only increases the cost of use, but also increases the complexity of use.

[0039] Manually adjusting the position of the photographic device requires the real-time participation of the photographer on the one hand, and on the other hand, it is impossible to stably control the movement speed of the photographic device and the stability of the picture, which greatly increases the difficulty of shooting and is prone to defects in the shooting quality, resulting in a decrease in the user experience.

[0040] An embodiment of the present disclosure provides an electronic device, comprising: at least one body; an image acquisition device connected to the at least one body; and at least one driving device connected to the at least one body, wherein the at least one driving device is used to drive the body to move in a predetermined direction through the interaction of a magnetic field, and the image acquisition device can move along with the movement of the body.

[0041] According to the embodiment of the present disclosure, by utilizing the driving device of the electronic device itself, while driving the main body to move in a predetermined direction, the image acquisition device is driven to move synchronously. The mobile shooting of the image acquisition device can be realized without the aid of additional devices, making the image acquisition work of the image acquisition device more convenient. Not only does it save the use cost in the image acquisition process, but it can also maintain the stable movement of the image acquisition device and improve the user experience.

[0042] The following will be passed Figure 1-5B The electronic device according to the embodiment of the present disclosure is described in detail.

[0043] Figure 1 The structural diagram of an electronic device according to an embodiment of the present disclosure is schematically shown.

[0044] like Figure 1 As shown, the electronic device 10 of the embodiment of the present disclosure includes: at least one body 11, an image acquisition device 12 and at least one driving device 13.

[0045] The image acquisition device 12 is connected to at least one body 11 .

[0046] At least one driving device 13 is connected to at least one main body 11 , and is used to drive the main body 11 to move in a predetermined direction through the interaction of a magnetic field. The image acquisition device 12 can move along with the movement of the main body 11 .

[0047] The electronic device 10 of the embodiment of the present disclosure may be any device with an image acquisition function, for example, a mobile phone, a tablet computer, a wearable device such as a smart watch, and other electronic devices. The electronic device 10 of the embodiment of the present disclosure may also have a foldable form or a retractable scroll form. However, the embodiment of the present disclosure does not impose any special restrictions on the specific device form of the electronic device 10.

[0048] The body 11 may be a collection of components that can realize different functions of the electronic device 10. For example, the body 11 may be a mobile phone body 11, a notebook computer body 11, and the like.

[0049] The electronic device 10 may be a device having one body 11. For example, a tablet computer having one body 11. The electronic device 10 may also be a device having multiple bodies 11. For example, a folding screen mobile phone having three bodies 11, a laptop computer having two bodies 11, etc. It should be noted that the embodiment of the present disclosure does not specifically limit the number of bodies 11 of the electronic device 10, and it is only required that the electronic device 10 has an image acquisition function.

[0050] The image acquisition device 12 is a device integrated on the electronic device 10 and having an image acquisition function, for example, a camera on a mobile phone, a camera on a laptop, etc. Similarly, the embodiment of the present disclosure does not limit the specific position of the image acquisition device relative to the electronic device.

[0051] The driving device 13 may be a device disposed on the body 11 and capable of driving the body 11 to move in a predetermined direction. The driving device 13 may be a device capable of driving the body 11 through the interaction of magnetic fields. For example, the driving device 13 may be a linear motor installed in the mobile phone itself.

[0052] The predetermined direction may be any direction in space. For example, the drive device 13 may drive the body 11 to make an arc motion in a clockwise direction. The drive device 13 may also drive the body 11 to make an arc motion in a counterclockwise direction. The drive device 13 may also drive the body 11 to make a linear motion in a certain direction. Here, the drive device 13 may drive the body 11 to make motions in multiple predetermined directions. For example, a linear motor in a mobile phone may drive the mobile phone to make an arc motion in a clockwise or counterclockwise direction with the center of gravity of the mobile phone as the center of the circle.

[0053] Here, when the driving device 13 drives the body 11 to move in a predetermined direction, the body 11 moves, driving the image acquisition device 12 on the body 11 to move synchronously. At this time, the position of the image acquisition device 12 relative to the body 11 remains unchanged.

[0054] Under the same image acquisition conditions (acquisition environment, acquisition time, etc. are the same), the images (e.g., videos, pictures, etc.) acquired by the image acquisition device 12 in a moving state driven by the driving device described in the present disclosure contain more effective image information (e.g., pixels) than the images acquired by the image acquisition device 12 in a non-moving state.

[0055] In one example, continue to refer to Figure 1 The electronic device 10 may be a foldable electronic device, including a first body 11 and a second body 11, the first body 11 and the second body 11 are movably connected by a connecting device such as a rotating shaft, the first body 11 is in a folded or unfolded state with the second body 11 through the connecting device, and when in the folded state, the first body 11 at least partially covers the second body 11. The image acquisition device 12 is a camera, and the camera can be arranged on the outer surface of the first body 11 of the foldable device. The driving device 13 may be a linear motor, and the linear motor is arranged in the second body 11. In the process of using a mobile phone to perform dynamic time-lapse photography, the linear motor can drive the body 11 to make an arc motion along a predetermined direction (the first direction D1 or the second direction D2). The body 11 drives the camera to also make an arc motion along a predetermined direction, thereby realizing mobile shooting of the mobile phone camera.

[0056] It can be understood that by utilizing the driving device 13 of the electronic device 10 itself, while driving the body 11 to move in a predetermined direction, the image acquisition device 12 is driven to move synchronously. The mobile shooting of the image acquisition device 12 can be realized without the aid of additional devices, making the image acquisition work of the image acquisition device 12 more convenient. Not only does it save the use cost during the image acquisition process, but it can also maintain the stable movement of the image acquisition device 12, thereby ensuring the image acquisition effect and improving the user experience.

[0057] Figure 2 The schematic diagram shows the structure of a driving device according to an embodiment of the present disclosure.

[0058] like Figure 2 As shown, in one achievable manner, the driving device 13 of the embodiment of the present disclosure may include: a first driving component 131 .

[0059] The first driving component 131 includes at least one excitation coil 1311 and a moving component 1312. The excitation coil 1311 is used to generate a magnetic field after being energized to drive the moving component to drive at least one body 11 to reciprocate along a predetermined direction. The moving component 1312 includes at least a magnet 1312a and at least one elastic member 1312b.

[0060] Exemplarily, the first driving component 131 may be a linear motor. At least one excitation coil 1311 is wound around the outer surface of the magnet 1312a, the magnet 1312a is connected to the body 11, and the elastic member 1312b may be disposed on opposite sides of the magnet 1312a and arranged parallel to the magnet 1312a.

[0061] The magnet 1312a may be a permanent magnet or a soft magnet. The excitation coil 1311 may be a copper core coil, a ferrite coil, or an iron core coil. Of course, it may also be a coil of other materials, which is not limited in the embodiments of the present disclosure. The number of the excitation coils 1311 may be set based on experience or actual needs, such as 1, 2, or 3.

[0062] The elastic member 1312b may be a member capable of deformation and recovery, i.e., capable of elastic deformation, such as a spring, etc. The elastic member 1312b may limit the movement of the magnet 1312a to prevent the magnet 1312a from moving in directions other than the central axis direction of the excitation coil 1311.

[0063] When the excitation coil 1311 is energized, a magnetic field is generated inside the excitation coil 1311. Under the action of the magnetic force of the magnetic field, the magnet 1312a can reciprocate in the direction of the central axis inside the coil. Since the predetermined direction is one direction, in order to enable the body 11 to move in a predetermined direction (including the opposite first direction and the second direction) under the drive of the linear motor, the current can be adjusted to enable the body 11 to move in the predetermined direction.

[0064] For example, in order to realize dynamic time-lapse photography of a mobile phone camera, the mobile phone can be driven to move in a predetermined direction by a linear motor in the mobile phone. During the movement, if the mobile phone is to move in the first direction D1, when the magnet 1312a in the linear motor moves in the direction d1 corresponding to the first direction, the excitation coil 1311 is energized, and a magnetic field is generated inside the excitation coil 1311. Under the action of the magnetic force of the magnetic field, the magnet 1312a can move in the direction d1 corresponding to the first direction inside the coil, thereby driving the mobile phone to move in the first direction D1, thereby driving the camera to move in the first direction D1. When the magnet 1312a in the linear motor moves in the direction d2 corresponding to the second direction, the excitation coil 1311 is not energized, and the excitation coil 1311 does not generate a magnetic field, and cannot drive the mobile phone to move in the second direction D2. In one cycle (energized and not energized), the excitation coil 1311 can drive the magnet 1312a to move in the direction d1 corresponding to the first direction, but cannot drive the magnet 1312a to move in the direction d2 corresponding to the second direction. Therefore, the body 11 can always generate displacement along the first direction D1 in one cycle. In the accumulation process of multiple cycles, the body 11 can continuously generate displacement along the first direction D1 to achieve the movement of the body 11 along the first direction D1, thereby achieving the movement of the camera along the first direction D1.

[0065] It should be noted that the driving device moves in a straight line direction, and the body moves in an arc direction. When the center of gravity of the driving device and the center of gravity of the body do not coincide with each other, the driving device moves in a direction d1 corresponding to the first direction, which drives the body to move in the first direction D1 of the arc direction; and the driving device moves in a direction d2 corresponding to the second direction, which drives the body to move in the second direction D2 of the arc direction.

[0066] The video is made by playing photos one after another in rapid succession. The normal video frame rate is 25 frames per second, and the time-lapse photography may be 1 frame every 5 seconds, so the phone can be moved during the 5 seconds of pause. When the phone turns on the time-lapse photography, set the delay time and the speed of the movement angle, calculate the time between each two frames of video through data calculation, and then control the linear motor between the two frames of video to move or rotate the phone in a certain direction.

[0067] Furthermore, the above method can also be executed when the folding device is in the folded state and the time-lapse photography state is turned on, which can reduce friction and make the execution effect of the method better.

[0068] Linear motors convert electrical energy into kinetic energy. By controlling the direction of the current, the direction of movement of the vibrator inside the linear motor can be controlled, thereby converting electrical energy into kinetic energy. The kinetic energy overcomes friction and is converted into the displacement of the phone. Folding phones have low friction resistance when folded, and it is easier to control the displacement of the phone through the vibration of the linear motor. The linear motor controls the displacement of the phone by controlling the power-on duration, frequency, and amplitude of the electrical signal to control the linear motor's greater vibration intensity in a certain direction, thereby achieving unidirectional movement of the phone. The specific movement speed can also be controlled by controlling the vibration frequency and vibration intensity.

[0069] It can be understood that by utilizing the driving device 13 of the main body 11 and adjusting the working mode of the current, the mobile shooting of the image acquisition device 12 can be realized, and different shooting angles and dynamic effects can be realized more flexibly. At the same time, the use cost in the image acquisition process is greatly saved.

[0070] Figure 3 The schematic diagram shows the structure of a driving device according to another embodiment of the present disclosure.

[0071] like Figure 3 As shown, in another possible implementation, Figure 2 The electronic device 10 shown is Figure 3 The difference of the driving device 13 shown is that the driving device 13 also includes:

[0072] The second driving assembly 132 is used to increase or decrease the movement step of at least one body 11 according to the magnetic pole interaction while at least one body 11 moves in a predetermined direction.

[0073] Exemplarily, the second drive component 132 may be capable of generating two interacting magnetic fields, and according to the interaction between the magnetic fields, the first drive component 131 drives the stride of the body 11 to move in a predetermined direction to enhance or weaken. For example, the second drive component 132 may include two coils. One coil is located on the magnet 1312a, and one coil may be located on the body 11. When the two coils are energized, a current is generated, and the current generates a magnetic field. When the magnetic poles of the two magnetic fields are the same, the two coils repel each other. If at this time, the direction in which the magnet 1312a drives the body 11 is the same as the direction in which the two coils repel each other, the moving path of the body 11 can be increased. When the two coils are energized, a current is generated, and the current generates a magnetic field. When the magnetic poles of the two magnetic fields are opposite, the two coils attract each other. If at this time, the direction in which the magnet 1312a drives the body 11 is opposite to the direction in which the two coils attract each other, the moving path of the body 11 can be reduced.

[0074] Here, the first drive assembly 131 itself can realize the movement of the body 11 in a predetermined direction. The second drive assembly 132 can serve as an auxiliary structure to assist the first drive assembly 131 to move in a predetermined direction. The first drive assembly 131 and the second drive assembly 132 can work independently, that is, the input circuits of the first drive assembly 131 and the second drive assembly 132 can be different.

[0075] In one example, if the body 11 is to move along the first direction D1, the second drive assembly 132 works while the first drive assembly 131 drives the body 11 to move along the first direction D1, and the path (stride) of the body 11 moving along the first direction D1 becomes larger. When the first drive assembly 131 does not drive the body 11 to move along the second direction D2, the second drive assembly 132 may not work, so that the body 11 can move along the first direction D1.

[0076] In another example, if the body 11 is to move along the first direction D1, the second drive assembly 132 works when the first drive assembly 131 drives the body 11 to move along the first direction D1, and the path (stride) of the body 11 moving along the first direction D1 becomes larger. When the first drive assembly 131 drives the body 11 to move along the second direction D2, the second drive assembly 132 works, and the path (stride) of the body 11 moving along the second direction D2 becomes smaller. When the first drive assembly 131 is working normally, the paths of the body 11 driven by the first drive assembly 131 to move along the first direction D1 and the second direction D2 are the same. The second drive assembly 132 can make the path (stride) of the body 11 moving along the first direction D1 larger, and the path (stride) of the body 11 moving along the second direction D2 smaller. Then the path of the body 11 moving along the first direction D1 is always greater than the path of the body 11 moving along the second direction D2, and therefore, the body 11 can move along the first direction D1.

[0077] In one implementation, the second driving assembly 132 includes: a first component 132a.

[0078] The first component 132a is disposed on one side of the first driving component 131 along the first direction D1 or the second direction D2. If the first component 132a is disposed on one side of the first driving component 131 along the first direction D1, the first component 132a is used to increase or decrease the stride of at least one body 11 in the first direction D1; if the first component 132a is disposed on one side of the second driving component 132 along the second direction D2, the first component 132a is used to increase or decrease the stride of at least one body 11 in the second direction D2.

[0079] The predetermined direction includes a first direction D1 and a second direction D2 which are opposite to each other.

[0080] For example, the first component 132a may be capable of increasing or decreasing the movement step of at least one body 11 according to the magnetic pole interaction. For example, the first component 132a may be the two coils mentioned above.

[0081] When the first driving assembly 131 is a linear motor, the first component 132a can be disposed at the first end of the magnet 1312a (along the d1 direction corresponding to the first direction) or the second end of the magnet 1312a (along the d2 direction corresponding to the second direction).

[0082] For example, the first component 132a is disposed at the first end of the magnet 1312a. If the body 11 is to be moved in the first direction, during the process of the linear motor driving the body 11 to move in the first direction D1, the first component 132a works, and the first end of the magnet 1312a is brought closer to the body 11 by the effect of the magnetic poles attracting each other, thereby increasing the path (stride) of the body 11 moving in the first direction D1. During the process of the linear motor driving the body 11 to move in the second direction D2, the first component 132a works, and the second end of the magnet 1312a is prevented from approaching the body 11 by the effect of the magnetic poles attracting each other, thereby decreasing the path (stride) of the body 11 moving in the second direction D2. Therefore, in each cycle (the first driving component 131 drives the body 11 to move in the first direction D1 once and in the second direction D2 once), the path of the body 11 moving in the first direction D1 is always greater than the path of movement in the second direction D2, thereby achieving the movement of the body 11 in the first direction D1.

[0083] If the body 11 is to be moved in the second direction D1, during the process of the linear motor driving the body 11 to move in the first direction D1, the first component 132a works, and utilizes the effect of magnetic pole repulsion to prevent the first end of the magnet 1312a from approaching the body 11, thereby reducing the path (stride) of the body 11 moving in the first direction D1. During the process of the linear motor driving the body 11 to move in the second direction D2, the first component 132a works, and utilizes the effect of magnetic pole repulsion to make the second end of the magnet 1312a approach the body 11, thereby increasing the path (stride) of the body 11 moving in the second direction D2. Therefore, in each cycle (the first driving component 131 drives the body 11 to move in the first direction D1 once and in the second direction D2 once), the path of the body 11 moving in the second direction D2 is always greater than the path of movement in the first direction D1, thereby achieving the movement of the body 11 in the second direction D2.

[0084] In another possible implementation, the second driving assembly 132 further includes: a second component 132b.

[0085] The second component 132b is disposed on the opposite side of the first driving assembly 131 from the first component 132a. If the first component 132a increases the stride of at least one body 11 in the first direction, the second component 132b is used to reduce the stride of at least one body 11 in the second direction. If the first component 132a reduces the stride of at least one body 11 in the first direction, the second component 132b is used to increase the stride of at least one body 11 in the second direction.

[0086] Exemplarily, the second component 132b can be capable of increasing or decreasing the movement stride of at least one body 11 according to the magnetic pole interaction. For example, the second component 132b can be the two coils mentioned above. The second component 132b can be a component with the same structure as the first component 132a, but the second component 132b is arranged at a different position from the first component 132a.

[0087] Continue to refer to Figure 3 When the first driving component 131 is a linear motor, the first component 132a can be disposed at the first end of the magnet 1312a (along the d1 direction corresponding to the first direction), and the second component 132b can be disposed at the second end of the magnet 1312a (along the d2 direction corresponding to the second direction).

[0088] For example, the first component 132a is disposed at a first end of the magnet 1312a, and the second component 132b is disposed at a second end of the magnet 1312a.

[0089] If the body 11 is to move along the first direction D1, during the process of the linear motor driving the body 11 to move along the first direction D1, the first component 132a works, and the first end of the magnet 1312a is brought closer to the body 11 by the effect of the magnetic poles attracting each other, thereby increasing the path (stride) of the body 11 moving along the first direction D1. At the same time, the second component 132b can also work, and the first end of the magnet 1312a is brought closer to the body 11 by the effect of the magnetic poles repelling each other, thereby further increasing the path (stride) of the body 11 moving along the first direction D1. Compared with the case where only the first component 132a works, the first component 132a and the second component 132b work simultaneously, which can further increase the stride of the body 11 moving along the predetermined direction.

[0090] If the body 11 is to move along the first direction D1, during the process of the linear motor driving the body 11 to move along the second direction D2, the first component 132a works, and utilizes the effect of magnetic poles attracting each other to prevent the second end of the magnet 1312a from approaching the body 11, thereby reducing the path (stride) of the body 11 moving along the second direction D2. At the same time, the second component 132b can also work, and utilizes the effect of magnetic poles repelling each other to prevent the second end of the magnet 1312a from approaching the body 11, thereby further reducing the path (stride) of the body 11 moving along the second direction D2. Compared with the case where only the first component 132a works, the first component 132a and the second component 132b work simultaneously, which can further reduce the stride of the body 11 moving along the predetermined direction.

[0091] Therefore, in each cycle (the first driving component 131 drives the body 11 to move once in the first direction D1 and once in the second direction D1), the movement path of the body 11 along the first direction D1 is always greater than the movement path along the second direction D1, thereby realizing the movement of the body 11 along the first direction D1.

[0092] If the body 11 is to move along the second direction D2, during the process of the linear motor driving the body 11 to move along the first direction D1, the first component 132a works, using the effect of magnetic pole repulsion to prevent the first end of the magnet 1312a from approaching the body 11, thereby reducing the path (stride) of the body 11 moving along the first direction D1. At the same time, the second component 132b can also work, using the effect of magnetic pole attraction to make the first end of the magnet 1312a closer to the body 11, thereby further increasing the path (stride) of the body 11 moving along the first direction D2.

[0093] If the body 11 is to be moved in the second direction D2, during the process of the linear motor driving the body 11 to move in the second direction D2, the first component 132a works, and utilizes the effect of magnetic pole repulsion to prevent the first end of the magnet 1312a from approaching the body 11, thereby reducing the path (stride) of the body 11 moving in the second direction D1. At the same time, the second component 132b can also work, and utilizes the effect of magnetic pole attraction to make the second end of the magnet 1312a closer to the body 11, thereby further increasing the path (stride) of the body 11 moving in the second direction D2.

[0094] Therefore, in each cycle (the first driving component 131 drives the body 11 to move once in the first direction D1 and once in the second direction D2), the movement path of the body 11 along the second direction D2 is always greater than the movement path along the first direction D1, thereby realizing the movement of the body 11 along the second direction D2.

[0095] It is understandable that the use of an asymmetric drive device to achieve asymmetric movement can not only achieve unidirectional displacement of the electronic device, but also further improve the vibration effect of the electronic device. At the same time, through current control, the time required for the drive device to stop vibrating can be shortened, reducing the dragging feeling and providing a more diverse and delicate touch feedback experience.

[0096] Figure 4A One of the working schematic diagrams of the driving device according to an embodiment of the present disclosure is schematically shown.

[0097] According to the embodiment of the present disclosure, the first component 132 a includes: a first coil 1321 and a second coil 1322 .

[0098] The first coil 1321 is disposed around one end of the first driving component 131 ; the second coil 1322 is disposed on one side of at least one body 11 close to the first coil 1321 .

[0099] Among them, when the first component 132a reduces the step of the first driving component 131 in the first direction D1, the polarity of the first magnetic field generated by the first coil 1321 and the second magnetic field generated by the second coil 1322 are close to each other; when the first component 132a increases the step of the first driving component 131 in the first direction D1, the polarity of the first magnetic field generated by the first coil 1321 and the second magnetic field generated by the second coil 1322 are opposite to each other.

[0100] For example, refer to Figure 4A In the case where the first driving component 131 is a linear motor, the second driving component 132 may include a first component 132a and a second component 132b, wherein the first component 132a is disposed at a first end of a magnet 1312a of the first driving component 131, and the second component 132b is disposed at a second end of the magnet 1312a of the first driving component 131. The first component 132a includes a first coil 1321 and a second coil 1322, and the second component 132b includes a third coil and a fourth coil.

[0101] The first coil 1321 is wound around the first end of the magnet 1312a, the second coil 1322 is wound around the body 11 near the first end of the magnet 1312a, the third coil is wound around the second end of the magnet 1312a, and the fourth coil is wound around the body 11 near the second end of the magnet 1312a.

[0102] If the body 11 is to be moved in the first direction D1, during the process of the linear motor driving the body 11 to move in the first direction D1, the first component 132a works to control the current at both ends of the first coil 1321 and the second coil 1322 to be turned on, so that the magnetic poles of the magnetic field generated on the side where the first coil 1321 and the second coil 1322 are close to each other are opposite, and the first end of the magnet 1312a is closer to the body 11 by the effect of the magnetic poles attracting each other, so that the path (stride) of the body 11 moving in the first direction D1 becomes larger. At the same time, the second component 132b can also work to control the current at both ends of the third coil and the fourth coil to be turned on, so that the magnetic poles on the side where the third coil and the fourth coil are close to each other are the same, and the first end of the magnet 1312a is closer to the body 11 by the effect of the magnetic poles repelling each other, so that the path (stride) of the body 11 moving in the first direction D1 is further increased.

[0103] If the body 11 is to be moved in the first direction D1, during the process of the linear motor driving the body 11 to move in the second direction D2, the first component 132a works to control the current at both ends of the first coil 1321 and the second coil 1322 to be turned on, so that the magnetic poles of the magnetic field generated on the side where the first coil 1321 and the second coil 1322 are close to each other are opposite, and the effect of the magnetic poles attracting each other is used to prevent the second end of the magnet 1312a from approaching the body 11, thereby reducing the path (step) of the body 11 moving in the second direction D2. At the same time, the second component 132b can also work to control the current at both ends of the third coil and the fourth coil to be turned on, so that the magnetic poles on the side where the third coil and the fourth coil are close to each other are the same, and the effect of the magnetic poles repelling each other is used to further prevent the second end of the magnet 1312a from approaching the body 11, thereby further reducing the path (step) of the body 11 moving in the second direction D2.

[0104] If the body 11 is to be moved in the second direction D2, during the process of the linear motor driving the body 11 to move in the first direction D1, the first component 132a works to control the current at both ends of the first coil 1321 and the second coil 1322 to be turned on, so that the magnetic poles of the magnetic field generated on the side where the first coil 1321 and the second coil 1322 are close to each other are the same, and the effect of the magnetic poles repelling each other is used to prevent the first end of the magnet 1312a from approaching the body 11, thereby reducing the path (step) of the body 11 moving in the first direction D1. At the same time, the second component 132b can also work to control the current at both ends of the third coil and the fourth coil to be turned on, so that the magnetic poles on the side where the third coil and the fourth coil are close to each other are opposite, and the effect of the magnetic poles attracting each other is used to further prevent the first end of the magnet 1312a from approaching the body 11, thereby further reducing the path (step) of the body 11 moving in the first direction D1.

[0105] If the body 11 is to be moved in the second direction D2, during the process of the linear motor driving the body 11 to move in the second direction D2, the first component 132a works to control the current at both ends of the first coil 1321 and the second coil 1322 to be turned on, so that the magnetic poles of the magnetic field generated on the side where the first coil 1321 and the second coil 1322 are close to each other are the same, and the second end of the magnet 1312a is brought close to the body 11 by the effect of magnetic pole repulsion, thereby increasing the path (stride) of the body 11 moving in the second direction D2. At the same time, the second component 132b can also work to control the current at both ends of the third coil and the fourth coil to be turned on, so that the magnetic poles on the side where the third coil and the fourth coil are close to each other are opposite, and the second end of the magnet 1312a is brought close to the body 11 by the effect of magnetic pole attraction, thereby further increasing the path (stride) of the body 11 moving in the second direction D2.

[0106] Therefore, in each cycle (the first driving component 131 drives the body 11 to move once in the first direction D2 and once in the second direction D2), the movement path of the body 11 along the first direction D1 is always greater than the movement path along the second direction D2, thereby realizing the movement of the body 11 along the first direction D1.

[0107] For example, when the two ends of the excitation coil 1311 of the first drive component 131 are not energized, it is an ordinary linear motor. When the vibration of the main body 11 in the first direction is required to be stronger and the vibration in the second direction is weaker, when the magnet 1312a moves to the second direction, by controlling the opening of the current at both ends, the electromagnetic field at the second end has the same polarity to generate a reaction force, which hinders the movement of the magnet 1312a, and the electromagnetic field at the first end has the opposite polarity to generate an attraction line, which also hinders the movement of the magnet 1312a. The two work together to reduce the kinetic energy provided by the collision of the magnet 1312a in the second direction, and the kinetic energy transmitted to the main body 11 by the collision linear motor body is also reduced accordingly.

[0108] Figure 4B The second working schematic diagram of the driving device according to the embodiment of the present disclosure is schematically shown.

[0109] Reference Figure 4B In one example, a linear motor converts electrical energy into kinetic energy. By controlling the direction of the current, the direction of movement of the magnet 1312a inside the linear motor can be controlled, thereby converting electrical energy into kinetic energy. The kinetic energy overcomes the friction force and is converted into the displacement of the mobile phone. The friction resistance of a foldable mobile phone is small in the folded state, and it is easier to control the displacement of the mobile phone through the vibration of the linear motor. The linear motor controls the displacement of the mobile phone by controlling the power-on duration, frequency and amplitude of the electrical signal to control the linear motor to have a greater vibration intensity in a certain direction, thereby achieving unidirectional movement of the mobile phone. The specific movement speed can also be controlled by controlling the vibration frequency and vibration intensity. Figure 5AOne of the layout diagrams of the electronic device and the driving device according to the embodiment of the present disclosure is schematically shown; Figure 5B The second schematic diagram of the layout of the electronic device and the driving device according to the embodiment of the present disclosure is schematically shown.

[0110] According to an embodiment of the present disclosure, at least one body 11 has a target area, and the target area represents the center of gravity 111 of the at least one body 11. At least one driving device 13 is arranged at the target position of the at least one body 11. The target position does not belong to the target area, and the at least one driving device 13 is arranged coplanar with the center of gravity 111 of the at least one body 11.

[0111] The target area is associated with the posture of at least one body 11. As the posture of at least one body 11 changes, the center of gravity 111 of at least one body 11 will also change accordingly. The changing center of gravity 111 constitutes the target area. For example, in a folding mobile phone, when the first body 11 and the second body 11 of the folding mobile phone are at different opening and closing angles, the center of gravity 111 of the folding mobile phone will also be different. For example, when the first body 11 and the second body 11 of the folding mobile phone are at 90 degrees, there is a first center of gravity 111. When the first body 11 and the second body 11 of the folding mobile phone are at 180 degrees, there is a second center of gravity 111. When the first body 11 and the second body 11 of the folding mobile phone are at 0 degrees, there is a third center of gravity 111. Then the target area includes at least the first center of gravity 111, the second center of gravity 111 and the third center of gravity 111.

[0112] The center of gravity 111 of the driving device 13 and the center of gravity 111 of the body 11 are located in the same plane.

[0113] In order to ensure that the driving device 13 on the body 11 can drive the body 11 to move in a predetermined direction, the center of the driving device 13 does not coincide with the center of gravity 111 of the body 11. Figure 5A As shown, when the electronic device 10 has a driving device 13 and the first body 11 and the second body 11 of the foldable mobile phone are at 90 degrees, the driving device 13 and the center of gravity 111 of the body 11 do not coincide. Figure 5B As shown, when the electronic device 10 has two driving devices 13 and the first body 11 and the second body 11 of the foldable mobile phone are at 90 degrees, the two driving devices 13 do not coincide with the center of gravity 111 of the body 11.

[0114] For example, as the position of the mobile phone or the degree of folding changes, the center of gravity 111 of the mobile phone will change. In order to maximize the scene framing of the mobile phone time-lapse photography, the mobile phone can be rotated under the drive of the driving device 13. The condition for rotation is that the position of the driving device 13 does not coincide with the center of gravity 111 of the mobile phone. When driving, the center of gravity 111 of the mobile phone and the driving device 13 are located in the same plane, and the driving device 13 can drive the mobile phone to rotate in the first direction or the second direction.

[0115] According to an embodiment of the present disclosure, for example, Figure 1 The electronic device 10 shown may further include: a support assembly;

[0116] The support assembly is detachably connected to at least one body 11 , and the support assembly is used to adjust the contact area between the at least one body 11 and the support assembly.

[0117] Exemplarily, the support assembly can be a device for carrying at least one body 11 when the image acquisition device 12 moves to shoot. For example, the support assembly can be a support seat, and one side of the support seat is provided with a groove for at least one body 11 to be snapped and adapted. The other side of the support seat is in contact with the placement table. Among them, the contact area between the other side of the support seat and the placement table is smaller than the contact area between the body 11 and the placement table. When the contact area is reduced, it is easier for the driving device 13 to drive the body 11 to move in a predetermined direction.

[0118] For example, if the friction between at least one body 11 and the table surface on which the body 11 is placed is large, the vibration intensity of the linear motor in the mobile phone is not enough to move the mobile phone. In this case, a support assembly can be installed for the mobile phone, which can reduce the contact area between the folded mobile phone and the table surface, making it easier for the linear motor to move the mobile phone by vibration intensity, so as to achieve mobile shooting of the mobile phone.

[0119] In other embodiments, the number of operations of the driving device 13 can be controlled to enable mobile shooting of the mobile phone when the friction between the main body 11 and the table surface on which the main body 11 is placed is large.

[0120] In other embodiments, the foldable mobile phone can also be placed on other smoother surfaces to achieve mobile shooting of the mobile phone.

[0121] The following will be passed Figure 6 The control method of the embodiment of the present disclosure is described in detail.

[0122] Figure 6 The flowchart of the control method according to the embodiment of the present disclosure is schematically shown.

[0123] like Figure 6 As shown, the control method of this embodiment includes operations S210 to S220.

[0124] In operation S210, in response to a shooting instruction of a user to an image acquisition device, a first working parameter of the image acquisition device for shooting is acquired, where the first working parameter includes a capture frequency.

[0125] In operation S220, based on the first working parameter, at least one driving device is controlled to drive the image acquisition device to move along a predetermined direction.

[0126] The control method implemented in the present disclosure is applied to the above-mentioned electronic device 10. The electronic device, the image acquisition device, and the driving device can all refer to the above-mentioned Figure 1 The description of is not repeated here.

[0127] The acquisition frequency can be the interval between two adjacent frames captured by the image acquisition device. For example, a video is made by playing a series of photos in quick succession. The normal video frame rate is 25 frames per second, and the time-lapse photography may be 1 frame every 5 seconds. Therefore, during the 5 seconds of pause, the electronic device body can be controlled by the driving device to move in a predetermined direction.

[0128] Exemplarily, the electronic device is a foldable phone. The shooting instruction starts the time-lapse shooting of the foldable phone. The first target parameter of the foldable phone is obtained: the time-lapse photography is 1 frame every 5 seconds and moves in the first direction. In the case of dynamic time-lapse photography using a foldable phone, during the 5s interval, the controller of the foldable phone controls the linear motor to move in the first direction, thereby realizing the movement of the camera of the foldable phone in the first direction. For the specific implementation process of the linear motor moving in the first direction, please refer to the above Figure 2-4B . I will not go into details here.

[0129] It is understandable that by utilizing the driving device of the electronic device itself, while driving the main body to move in a predetermined direction, the image acquisition device is driven to move synchronously. The mobile shooting of the image acquisition device can be realized without the help of additional devices, making the image acquisition work of the image acquisition device more convenient. Not only does it save the cost of use during the image acquisition process, but it can also maintain the stable movement of the image acquisition device and improve the user experience.

[0130] As described above, when the first working parameter also includes information about the predetermined speed of the image acquisition device moving in a predetermined direction, in operation S210, the first working parameter captured by the image acquisition device is acquired. In an achievable manner, the operation may further include operation S211a.

[0131] In operation S211a, at least one driving device is controlled to drive at least one body to move along a predetermined direction on the target placement table, and first speed information is obtained as predetermined speed information.

[0132] In one example, the first working parameter may further include predetermined speed information. The predetermined speed information represents the movement distance of the main body on the target placement table per unit time. According to the predetermined speed information of the main body and the acquisition frequency, the distance moved by the image acquisition device within the interval time can be obtained, and the corresponding image shooting range can be known.

[0133] For example, a foldable mobile phone is placed on a real target platform, and a driving device is controlled in advance to drive the main body to move in a first direction for a period of time. The first speed information of the mobile phone moving on the target platform can be obtained. If the photographer determines that the first speed information meets the preset conditions (meets the shooting requirements), the first speed information can be used as the predetermined speed information. The shooting position of the mobile phone camera is adjusted and the shooting is performed again. The driving device is controlled to drive the main body to move in the first direction according to the first speed information to perform dynamic time-lapse photography.

[0134] It should be noted that if the purpose is to avoid the problem of image overlapping during mobile phone shooting, when the user wants to move the mobile phone along a first direction, the first drive component and / or the second drive component in the control drive device can be used to increase or decrease the step size of the mobile phone's movement in the first direction. However, if the mobile phone needs to be controlled not to move in the second direction, the first drive component and / or the second drive component in the control drive device will not work when the main body moves along the second direction.

[0135] If the purpose is to enable the mobile phone to record events at different times in a certain area, the first driving component and / or the second driving component in the driving device can be controlled to increase or decrease the step of the mobile phone in the first direction, or to increase or decrease the step of the mobile phone in the second direction. Adjustments can be made according to different application scenarios.

[0136] As described above, when the first working parameter also includes information about the predetermined speed of the image acquisition device moving in a predetermined direction, in operation S210, the first working parameter of the image acquisition device is acquired. In another achievable manner, the operation may further include operations S211b to S212b.

[0137] In operation S211b, at least one driving device is controlled to drive at least one body to move along a predetermined direction on the target placement table to obtain first speed information.

[0138] In operation S212b, in response to the user's editing operation on the first speed information, second speed information is obtained, and the second speed information is used as predetermined speed information, wherein the first speed information and the second speed information are different.

[0139] Exemplarily, a foldable mobile phone is placed on a realistic target placement table, and the driving device is pre-controlled to drive the body to move in the first direction for a period of time. The first speed information of the mobile phone moving on the target placement table can be obtained. If the photographer determines that the first speed information does not meet the preset conditions (meets the shooting requirements), the first speed information can be used as a reference to increase or decrease, obtain the second speed information, and use the second speed information as the predetermined speed information. And adjust the shooting position of the mobile phone camera and shoot again. The driving device is controlled to drive the body to move in the first direction according to the second speed information to perform dynamic time-lapse photography. For example, if the first speed information obtained in the trial run is 0.5cm / s, and the user feels that the mobile phone moves too fast under the first speed information, the movement speed can be reduced, and the first speed information 0.5cm / s is adjusted to the first speed information 0.2cm / s.

[0140] As described above, in operation S210, a first working parameter captured by the image acquisition device is obtained. In another achievable manner, the operation may further include operations S211c to S212c.

[0141] In operation S211c, a second operating parameter of the target placement platform is acquired, wherein the second operating parameter represents material information of a contact surface between the electronic device and the target placement platform.

[0142] In operation S212c, the second operating parameter is input into a preset model to obtain predetermined speed information.

[0143] For example, the predetermined speed information can be obtained by collecting an image of the target placement table through an image acquisition device, inputting the image into a preset model, and analyzing to obtain the speed information (predetermined speed information) of the electronic device moving on the target placement table. The preset model can be trained by sample data obtained by previously obtaining electronic devices moving on placement tables of different materials.

[0144] If the photographer determines that the predetermined speed information meets the preset conditions (meets the shooting requirements), the predetermined speed information can be used to adjust the shooting position of the mobile phone camera and reshoot. The driving device is controlled to drive the body to move along the first direction according to the predetermined speed information to perform dynamic time-lapse photography.

[0145] If the photographer determines that the predetermined speed information does not meet the preset conditions (meets the shooting requirements), the predetermined speed information can be used as a reference to increase or decrease the speed, and the updated predetermined speed information can be used as the predetermined speed information. The shooting position of the mobile phone camera can be adjusted to shoot again.

[0146] As described above, in operation S220, based on the first working parameter, at least one driving device is controlled to drive the image acquisition device to move along a predetermined direction. In one achievable manner, the operation may further include operation S221.

[0147] In operation S221, when the driving device is a linear motor, at least one driving device is controlled to drive the image acquisition device to move in a predetermined direction within an interval by adjusting a third working parameter of the electrical signal, wherein the third working parameter represents electrical signals of different waveforms.

[0148] For example, when the driving device drives the mobile phone to rotate in one direction, it can be achieved in two ways: by changing the electrical signal, the body can move in a predetermined direction according to different vibration waveforms of the electrical signal.

[0149] Linear motors convert electrical energy into kinetic energy. By controlling the direction of the current, the direction of movement of the vibrator (magnet) inside the linear motor can be controlled, thereby converting electrical energy into kinetic energy. The kinetic energy overcomes friction and is converted into the displacement of the phone. Folding phones have low friction resistance when folded, so it is easier to control the displacement of the phone through the vibration of the linear motor. The linear motor controls the displacement of the phone by controlling the power-on duration, frequency, and amplitude of the electrical signal to control the linear motor's greater vibration intensity in a certain direction, thereby achieving unidirectional movement of the phone. The specific movement speed can also be controlled by controlling the vibration frequency and vibration intensity.

[0150] Based on the above control method, the present disclosure also provides a control device. Figure 7 The device is described in detail.

[0151] Figure 7 The structural block diagram of the control device according to the embodiment of the present disclosure is schematically shown.

[0152] like Figure 7 As shown, the control device 400 of this embodiment includes an acquisition module 410 and a control module 420 .

[0153] The acquisition module 410 is used to respond to the user's shooting instruction for the image acquisition device and acquire the first working parameter of the image acquisition device, wherein the first working parameter includes the acquisition frequency. In one embodiment, the acquisition module 410 can be used to perform the operation S210 described above, which will not be described in detail here.

[0154] The control module 420 is used to control at least one driving device to drive the image acquisition device to move along a predetermined direction based on the first working parameter. In one embodiment, the control module 420 can be used to perform the operation S220 described above, which will not be described in detail here.

[0155] According to an embodiment of the present disclosure, any multiple modules in the acquisition module 410 and the control module 420 can be combined into one module for implementation, or any one of the modules can be split into multiple modules. Alternatively, at least part of the functions of one or more of these modules can be combined with at least part of the functions of other modules and implemented in one module. According to an embodiment of the present disclosure, at least one of the acquisition module 410 and the control module 420 can be at least partially implemented as a hardware circuit, such as a field programmable gate array (FPGA), a programmable logic array (PLA), a system on a chip, a system on a substrate, a system on a package, an application-specific integrated circuit (ASIC), or can be implemented by hardware or firmware such as any other reasonable way of integrating or packaging the circuit, or implemented in any one of the three implementation methods of software, hardware and firmware or in any appropriate combination of any of them.
